Privacy

Last updated: November 9, 2026

This page explains what happens to your information when you use the Cortex website and the Cortex app. Cortex is made by FLock.io.

This website

The website sets no cookies and runs no analytics or advertising scripts. Fonts and images are served from the same site. When you download Cortex, the file comes from GitHub, which has its own privacy policy.

The Cortex app

• Your data stays on your Mac. Files, chats, the knowledge base, meetings and settings are stored in a folder on your Mac.
• Model providers. When you ask Cortex to do something, the request goes to the model provider you chose, using your own API key. That provider's terms and privacy policy apply to what it receives.
• Connectors. Apps you connect, such as Feishu or Google Drive, receive only the requests needed to do what you asked.
• No analytics. The app has no built-in usage analytics or crash reporting.
• Updates. The app checks GitHub for new versions.
• Cola on iPhone. Messages between your iPhone and your Mac are end-to-end encrypted. See the Cola privacy notice for details.

Custom builds

If we build or deploy Cortex for your organization, how data is handled is set out in our agreement with you.
